Install issues on Debian - "gem install pluto" method - sudo/root needed, plus depedencies

[taniwallach]

1. At least on Debian gem install pluto needs to be run as root.
   • sudo gem install pluto works (if proper dependencies are installed in advance).
2. Please consider adding a pointer/link to the install dependencies section of the FAQ in Step 1 of README.md (so people will see it before or right after running the gem install command) and maybe ask for contribution of similar lists for other systems.
3. On Debian - roughly the same dependencies are needed for gem install pluto as bundle install.
   • Dependencies: git ruby sqlite3 sudo gcc make libsqlite3-dev ruby-dev
   • ruby instead of ruby-bundler which pulled in ruby and ruby-bundler for the bundle install approach.

Once libsqlite3-dev and ruby-dev were installed both

• sudo gem install pluto
• luto build planet.ini -t starter -o build

completed successfully.

The first error before installing libsqlite3-dev ruby-dev but with git ruby sqlite3 sudo gcc make already installed in the minimal Debian image was:

HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.

If you are upgrading your Rails application from an older version of Rails:

Please check your Rails app for 'config.i18n.fallbacks = true'.
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
'config.i18n.fallbacks = [I18n.default_locale]'.
If not, fallbacks will be broken in your app by I18n 1.1.x.

If you are starting a NEW Rails application, you can ignore this notice.

For more info see:

Again thanks for the detailed report. I try to update the readme and will add a link back to this issue here.
